ELECTRIC WAFFLE IRON.

Original application filed May 2, 1925, Serial 1310. 27,428. Divided and this application filed December 21, 1925. Serial No. 76,575.

My invention relates to electricwaflie' One object of this invention is to provide a novel pivot-like joint for the electric wires which carry current tothe heating element for the upper member. Other objects appear hereinafter.

This application is a division of my application Serial No. 27,428, filed May 2, 1925. Referring to the accompanying drawings,

Fig. 1 is a side elevation of one form of my invention, with the upper griddle member closed; Fig. 2, a front elevation of the invention; Fig. 3, a'plan view of the same, 5 the upper griddle member being open; Fig.

4, a section on the line IV-IV on Fig. .3;

Fig. 5, a plan view of the rear portion of the invention with the cover omitted and parts being in section; Fig. 6, a section on the line 3 VIVI on Fig. 5.

On the drawings, I show a sheet-metal casing having the downwardly and rearwardly inclined back 1, the sides 2 and 3, the bottom 4, and the removable or swing- .ing front 5.

The lower griddle member 6, which is preferably made of aluminum, but may be cast-iron, closes the top of the casing and is secured thereto in any suitable manner as by the screws 7 which pass through the easing and into lugs 8 pendent from the mem- The upper griddle member 14 is adapted to register .with the member 6. The rear edges of the members 6 and 14 are provided respectively With the hinge-lugs 15 and 16,

which are pivoted together by the hingepins or screws 17.

.The upper face of the griddle member 14 is provided with the annular electric resistor or heating member 18 surrounding the boss 19 on the said member. A sheet-metal plate 20 overlies the resistor 18 and is held in place by the screw 21 passed through the plate and into the boss.

The lower face of the griddle member 6 is provided with the resistor 18' held m place by the plate 20' by the retaining screw 21' whichis passed into the member 6.

The upper face of the griddle member 14 has the upstanding flange 22 rising above the plate 20. Resting on the member 14 1s the'cover 23 made preferably of aluminum and having the flange 24 registering with between the hinge-lu the flange 22. The cover extends rearwardly to form the extension 25 which lies over the hinge-joints and curves downwardly for a distance behind them. its sides the lugs 26 which overlap the inner face of the flange 22 to which-they are secured by the screws 27. The cover has also the lug 28 pending from thefront thereof and overlapping the inner face of the flange 22. The handle 29 for operating the member 14 has at one end the screw 30 which passes through the flange 22 and into the lug 28, so that the handle not only operates the member 14-butalso holds the cover 23 thereon.

The rear edge 33 of the cover extension engages the lugs 34 on the hinge-lugs 15 when the upper griddle member 14 is swung upwardly and backwardly to its limit, as shown in Fig. 3.

35 is an electric control switch of any type which will make similar electric connections for heating the resistors 18 and-18 andfor lighting the lamps 36 and, 37. the complete circuits for these resistors and lamps being given in my said earlier application and'not claimed herein.

The cover has at- All the wiring system is beneath the lower griddle member 6 except the resistor 18, to-

rear edge of the griddle. member 6 and thence through the hollow L-shaped' member 59, thence through the hollow L-shaped member, 60, and into the rear edge of the griddle member 14.

The outer open ends of the members 59 and 60 face each other, the member 59 having in its end the circular recess 61'which receives the annular projection 62 on the end of the member 60. The axial centers of the pivot pins 17 and the described pivotlike joint between the members 59 and 60- are in'a straight line, so that when the griddle member 14 is oscillated, the projection 62 turns, in the recess 61 without'bindin'g.

On Fig. 5,-itv is shown that the distance the distance between the outer'faces of the 16 is greater than hinge-lugs. 15, the difference between these distances being at least equal to the length of the projection 62.' assembling the griddle member 14 with the griddle member 6, the hinge-lugs are arranged with the lugs 15 between thelugs 16, but the hingelug 15 which ison the opposite side of the member 59 from the pro ection 62 is first laced close to the adjacent hinge-lug 16. lhen the griddle memberM is'slid so as to cause the projection 62 to enter the recess 61. Then the hinge pins 17 are inserted through the lugs 16 and screwed into the lugs'15, but before the pin nearest the lower part of Fig. is inserted a washer 63 is placed between the lower hinge members and 16, the washer being as thick as the projection 62 islong. The latter hinge pinextends through the hole in the washer, which prevents lateral movement of the upper griddle member.

I claim'-:-- 1. In an electric heater, a lower member, an upper member, pivotally connected pairs of hinge lugs for the membersfa resistor for the upper member, two hollow L-shaped conduits connected respectively with the members and inde endent of and between 'the said pairs of huge lugs, the outer ends of the conduits facing each other and having their axial centers in alinement' with the axial centers of the hinge pivots, and electric conductors passing through the two conduits and connected to the resistor.

2. In an electric heater, a lower member,

' an upper member, pivotally connected pairs of huge lugs for the members, a resistor for the upper member, two hollow L-shaped conduits connected respectively with the members and-independently of and between the said pairs of hingelugs, the outer ends of the conduits facing each other and having their axial centers in alinement with the axial centers ofthe hinge pivots, electric conductors passing through ther-twoconduits and connected to the resistor, and a telescop- 1c connection between the said ends of the L-shaped members. 3, In an electric heater, a lower member,

an upper member, pivotally connected pairs-- of hinge lugs for the members, a resistor for the upper member, two hollow L-shaped conduits connected respectively with the members and hide ndent of and between the said pairs of h nge lugs, the outer ends of the conduits facing each-other and havthe upper member, two hollow L-shaped conduits connected respectively with the members and independent of and betweenthe said pairs of hinge lugs, the outer ends of the conduits facing each other and having their'axial centers in alinement with the axial centers of the hinge pivots, electric conductors passing through the two conduits and connected to the resistor, a telescopic connection between the said ends of the L- shaped'member, and a washer inserted between appropriate hinge lugs to prevent the separation of the said connection;
